Recent advances in pharmacotherapy for epilepsy.

PURPOSE OF REVIEW: Epilepsy affects 70 million people worldwide and is a significant cause of morbidity and early mortality. The mainstay of therapy is oral medications. Epilepsy drug development is escalating, driven by continued drug resistance in up to a third of epilepsy patients. Treatment development now focuses on discovery of novel mechanisms of action and syndrome-specific therapies. RECENT FINDINGS: Difficult-to-treat epilepsy related to conditions including tuberous sclerosis complex (TSC), Lennox Gastaut syndrome (LGS) and Dravet syndrome (DS) have been the target of recent developments. Disease-modifying therapy for epilepsy related to TSC with vigabatrin at onset of first electroencephalographic epileptiform changes, rather than after first clinical seizure, has demonstrated strongly positive seizure and developmental outcomes. Fenfluramine, approved for DS and, more recently, LGS, has robust data supporting efficacy, safety/tolerability, as well as mortality, quality of life and cognitive function. Rescue therapy has expanded to include better tolerated benzodiazepines in the form of nasal midazolam and valium. Cenobamate, a first-in-class inactivator of the persistent voltage-gated sodium channel and approved for adult partial onset epilepsy, has exceptional efficacy and tolerability and will be expanded to children and to generalized onset epilepsy in adults. SUMMARY: The repertoire of available and developmental therapies for epilepsy is rapidly expanding, and now includes disease-modifying vigabatrin in TSC and agents with extraordinary efficacy, fenfluramine and cenobamate.

Functional gallbladder disorder: Interim analysis of a prospective cohort study.

BACKGROUND: Functional gallbladder disorder (FGBD) remains a controversial indication for cholecystectomy. METHODS: A prospective cohort study enrolled patients strictly meeting Rome criteria for FGBD, and cholecystectomy was performed. They were assessed pre- and 3 and 6 months postoperatively with surveys of abdominal pain and quality of life (RAPID and SF-12 surveys, respectively). Interim analysis was performed. RESULTS: Although neither ejection fraction nor pain reproduction predicted success after cholecystectomy, the vast majority of enrolled patients had a successful outcome after undergoing cholecystectomy for FGBD: of a planned 100 patients, 46 were enrolled. Of 31 evaluable patients, 26 (83.9 â€‹%) reported RAPID improvement and 28 (93.3 â€‹%) SF12 improvement at 3- or 6-month follow-up. CONCLUSION: FGBD, strictly diagnosed, should perhaps no longer be a controversial indication for cholecystectomy, since its success rate for biliary pain in this study was similar to that for symptomatic cholelithiasis. Larger-scale studies or randomized trials may confirm these findings.
